The easiest way to capture this stream is to use our ``statistics_writer``, which will capture the statistics and store them in HDF5 file(s): the writer recognised packet boundaries, converts the packets into their respective matrix, and store a matrix for each received timestamp. Furthermore, packet header information is periodically recorded as HDF5 attributes::
The easiest way to capture this stream is to use our ``statistics_writer``, which will capture the statistics and store them in HDF5 file(s). The writer:
- computes packet boundaries,
- processes the data of each packet, and stores their values into the matrix relevant for the mode,
- stores a matrix per timestamp,
- stores packet header information per timestamp, as HDF5 attributes,
- writes to a new file at a configurable interval.
